Summary: In this study, flexible and rigid polyurethane/copper composites were prepared via a simple solution casting process. The dispersion and chemical bonding of the filler were investigated, and the thermal properties and mechanical properties of the composites were analyzed. The results showed that the thermal conductivity of the composites was significantly improved compared to the pure polyurethane, and the mechanical properties were also enhanced. The study suggests that copper microparticles can serve as an active filler in both flexible and rigid polyurethane matrices.

Summary: In order to meet the diversified requirements for polymer-based composites in modern electronic devices and electrical systems, the simultaneous enhancement of thermal-electrical-mechanical properties is a great challenge. The gradient structured composites, designed by adjusting the distribution of temperature, electric and stress fields in polyethylene (PE) based composites with different Al2O3 contents, demonstrated superior through-plane thermal conductivity, high breakdown strength, and good tensile strength. Finite element simulation provided evidence for the action mechanism on gradient structure regulating temperature and electric field. The strategy of constructing gradient structure provides a feasible route to meet the comprehensive performance requirements of PE based composites in massive manufacture scenario for practical insulation applications.

Summary: This paper investigates the residual mechanical properties and damage states of ambient cured wet layup carbon fiber reinforced epoxy composites exposed to elevated temperature regimes. The results show that high temperature conditions lead to the deterioration of resin characteristics and the bond between fibers and resin. This is a weakness in layered composites formed from unidirectional fabric architectures. Changes in failure modes are correlated through microscopy to damage progression at the fiber-matrix interface and resin levels. Differential scanning calorimetry is used to determine transitions in glass transition temperature, which indicate changes in damage mechanisms.

Summary: Thermoplastic all-polymer composites, made from the same material for reinforcing fibers and matrix material, have become increasingly popular due to their potential for recycling compared to traditional composites with inorganic reinforcements. This study proposes a new preparation concept for all-polyamide composites using a hybrid yarn of polyamide-6 and polyamide-66 fibers. By embroidering the hybrid yarn in the desired direction on a polyamide-6 fabric, composites with desired reinforcing fiber orientation can be prepared, maintaining the integrity of the reinforcing and unmelted PA66 fibers embedded in a molten PA6 matrix during thermoforming at 230 degrees C. The mechanical properties of these composites, including different matrix-to-reinforcement ratios and reinforcing fiber orientations, are characterized using quasi-static and high-speed tensile tests as well as penetration tests.

Summary: In recent years, various commercial coatings based on fluorinated materials have been developed using different preparation routes. However, these techniques often require expensive and complex equipment, involve multiple manufacturing steps, or are time- or cost-consuming. This study aimed to develop sustainable hydrophobic and transparent fluorinated hybrid coatings using the sol-gel method, which offers advantages such as lower cost, energy consumption, and easier implementation. The influence of perfluorooctanoic acid in the sol-gel process on the properties of the coatings was evaluated, and different silane precursors were used to synthesize hybrid silica materials. The fluorinated silica coatings showed good transparency and hydrophobicity, making them suitable for potential optical devices.

Summary: This study proposes a facile method to improve the performance of PLA for biomedical applications by incorporating different mass proportions of POSS nanoparticles with AH-POSS substituent using a melt-blending technique. The results show that AH-POSS has simultaneous nucleation and plasticizing effects on PLA nanohybrids, enhancing thermal resistance and easy control of crystallinity while maintaining PLA's biocompatibility. An interesting effect of AH-POSS on the mechanical properties of PLA at body temperature is observed. The PLA/AH-POSS nanohybrids obtained by melt compounding show considerable potential in the fabrication of biomedical devices.

Summary: In this study, poly(3-hydroxybutyrate) (PHB) was blended with medium-chain-length PHAs (mcl-PHAs) as an improvement in flexibility. Nanocellulose (NC) was added as a reinforcing agent. The use of different mcl-PHAs (PHO and PHN) had varied effects on the morphology, thermal, mechanical, and biodegradation behaviors of the PHB, especially with the presence of NC. The addition of mcl-PHAs decreased the storage modulus (E') of PHB blends, but the further addition of NC mitigated this decrease.

Summary: Obtaining photocatalytic coatings on textile materials is challenging due to the conflicting properties that need to be achieved. This study proposes a solution using hybrid silica films generated by sol-gel processes, containing TiO2 sensitized with iron (III) phthalocyanine (FeTCPc). The coatings were made using a pad-dry-cure process with various agents. Experimental results show that treatment with BORAX improves the resistance of the coatings to wet treatments but impairs their photocatalytic performances.

It is found that the size of the impactor affects the turning point of the compression strength. Additionally, high impact energy leads to damage in the bottom face sheet and reduces the overall compression strength.

Summary: This study investigates the effects of fibre concentration on the mechanical response of welded glass-fibre-reinforced polypropylene (GF-PP). Experimental observations reveal a significant reduction in weld ratio, up to 60%, indicating a decreased strength compared to the bulk material. Increasing fibre content in the welded material results in a decrease in stress at break and strain at the maximum stress. The use of DIC technique and X-ray microtomography further confirms the localized strain amplification in the welded zone due to the significant increase in fibre density.

Thus, appropriate approaches need to be implemented to enhance the fire safety of NFCs. This review summarizes and discusses the latest understanding of flammability and thermal properties of natural fibers, with a special focus on their interaction with polymer matrix in fire behavior. Additionally, the latest developments in flame-retardant approaches for NFCs are reviewed, covering both flame retardancy and fire structural integrity. Finally, future prospects and perspectives on fire safety of NFCs are proposed, providing insights into further advancements of NFCs.

Summary: Real-time monitoring of carbon fibre composites during Automated Fibre Placement (AFP) manufacturing remains a challenge for non-destructive evaluation (NDE) techniques. This study designed a directional eddy-current (EC) probe to evaluate the detectability of out-of-plane wrinkles. Experimental evaluations and finite element modeling were conducted to better understand the relationship between eddy-current density and defect detection. The findings suggest that the probe configuration with an asymmetric driver coil and differential pickup coils shows the best capability for wrinkle detection.
